Ever wonder why stalled fans can tear themselves apart? Here's a real-world insight into the phenomenon of fan surge and stalling - A few years ago, a 60-inch plenum fan in a pharmaceutical building in Puerto Rico tore itself apart overnight. Why? The fan continued to operate against closed dampers, a situation known as "dead heading," leading to severe mechanical stress and eventual failure. Fan blades stall individually, creating a microclimate of pressure fluctuations. This can cause the entire system to "rock and roll," with air output varying dramatically from one side to another. Such conditions not only strain the system but can lead to catastrophic failure when least expected – often overnight when no one is around to notice! Remember, HVAC systems are like flying fatigue tests; they need regular checks to prevent surprises. Don't let your system fail when you least expect it!

Introducing the Superior S600 Vacuum Degasser from Spirotherm, Inc. Hobbs & Associates, Inc. is proud to represent Spirotherm, Inc. in Virginia and Alabama, bringing you the latest in high-efficiency vacuum degassing technology! Air trapped in fluid systems can wreak havoc, causing decreased efficiency, excessive wear, and frequent maintenance. This air can lead to corrosion, noisy operation, and fluctuating pressure readings, ultimately damaging expensive components or even complete system failure. Proper air separation is the only effective solution to these issues. High-Efficiency Vacuum Degassing with the Superior S600 The Superior S600 offers two methods for removing gases from heating, cooling, or process water systems: 1. Passive Degassing: Dissolved gases are naturally released using the system's inherent temperature and pressure differences. With a Spirovent coalescing air separator, these gases are extracted from the liquid at the point of lowest solubility (lowest pressure/highest temperature). 2. Active Degassing (Vacuum Degassing: By creating a pressure change, a portion of the system fluid is temporarily placed in a vacuum state, releasing, separating, and removing dissolved gases. This treated fluid then reabsorbs air from the system for subsequent removal. When Does Vacuum Degassing Make Sense? - When an inline air separator cannot be installed at the desired location or is only too expensive. - In systems with many branches and partially low flow rates, where free collected air may not be carried to the air separator. - To eliminate air from make-up water before introducing it into the system. - In systems with significant elevation differences (e.g., multi-story buildings). Learn more about how the Superior S600 can revolutionize your HVAC system efficiency and reliability.

As HVAC professionals, working in high temperatures is part of the job, but it’s essential to prioritize safety to avoid heat-related illnesses. At Hobbs & Associates, Inc., we emphasize safety as a core value, not just a commitment. Let's prioritize safety this season, equipping ourselves with best practices to stay healthy and perform at our best. Here are some best practices to help you stay safe this summer: - Stay Hydrated: Drink plenty of water throughout the day, even if you don't feel thirsty. Consider electrolyte drinks to replenish minerals lost through sweating. - Take Frequent Breaks: Step away from hot work environments regularly to allow your body temperature to normalize. -Dress Appropriately: Wear light-colored, loose-fitting, breathable clothing. Use sun protection like hats and sunscreen for outdoor work. - Know the Signs of Heat-Related Illness: Be aware of symptoms like dizziness, headache, nausea, and confusion that could indicate heat exhaustion or heat stroke. - Use Proper PPE: Wear safety glasses, gloves, and other necessary PPE, but be mindful that some equipment can increase heat retention. - Schedule Wisely: Try to do the most strenuous work during cooler parts of the day when possible. - Acclimatize Gradually: Allow your body to adjust to working in heat, especially at the beginning of hot seasons. - Watch Out for Coworkers: Keep an eye on fellow technicians and know how to respond if someone shows signs of heat-related illness. -Ensure Proper Ventilation: When working in confined spaces, use fans or other means to improve air circulation. - Stay Informed About Weather Conditions: Be aware of heat advisories and take extra precautions on extremely hot days. By implementing these practices, HVAC technicians and manufacturing professionals can mitigate heat-related risks and ensure safer work conditions in high temperatures. Prioritizing safety is crucial in challenging environments, as heat stress can lead to serious medical conditions, including heat cramps, exhaustion, stroke, and even death. However, with proper planning, hydration, and awareness, these risks can be effectively prevented. Let's make this summer a safe and enjoyable one for everyone. Stay cool, stay hydrated, and stay informed about heat safety precautions. For more articles like this, please visit: https://lnkd.in/em363Bi9 #HVAC #SafetyTips #HVACR

Ready to optimize your HVAC system's performance by mastering your cooling coil's condensate GPM? Here's an example of calculating a cooling coil's condensate flow rate in gallons per minute, specifically at 1,000 cfm. For this lesson, let's assume you have an air-handling unit with the following conditions: Airflow = 1,000 cfm - Coil EAT = 95F db / 78F wb - Coil LAT = 50F db / 49.5F wb How much condensate is this cooling coil producing in gallons per minute? Here is the solution: First, determine the grains per pound of dry air for each condition. You can use your psychrometric chart or a psychrometric calculator to do this. - EAT = 117.4 grains/lb of dry air - LAT = 51.6 grains/lb of dry air Second, calculate how many grains have been removed. 117.4 - 51.6 = 65.74 grains/lb of dry air Third, let's convert this to lbs per minute as follows. 65.74 grains/lb of dry air x (0.075 lb air / ft3) x (1,000 ft3/min) x (1 lb / 7000 grains) = 0.704 lb / min Since there are 8.34 lbs of water per gallon, we can now calculate the GPM. The condensate flow rate is 0.704 / 8.34 = 0.08 gallons per minute. Which is about 42.3 lbs/hr or 5 gallons/hr of cooling coil condensate flow rate.
